Mountainous highway bridge drainage port mounting method
The invention relates to an installation method of a mountain highway bridge drainage port, which comprises the following steps of: determining the minimum value of a synthetic slope on a bridge flooras the position of the drainage port, forming a water collecting tank at the position of the drainage port, communicating the bottom end of the water collecting tank with a goose-shaped pipe, and installing an intermittent drainage device between the water collecting tank and the goose-shaped pipe. By the adoption of the technical scheme, the drainage port is formed in the lowest point of the bridge obtained through calculation, so that accumulated water is drained from the drainage port, the drainage rate is increased, accumulation of the accumulated water on the bridge floor is reduced, andinfluences on driving and the durability of the bridge are reduced. Forced siphoning is formed through the goose-shaped pipe, the speed of accumulated water passing through the goose-shaped pipe canbe increased, and therefore the situation that soil, leaves and the like in the accumulated water remain in the goose-shaped pipe or the water collecting tank is reduced under the siphoning effect, the anti-blocking effect is achieved, and bridge floor drainage is further facilitated.
本发明涉及提供一种山区公路桥梁排水口的安装方法，通过确定桥面上合成坡度的最小值为排水口位置，并在排水口位置开设有集水槽，集水槽底端连通有鹅型管，集水槽与鹅型管之间安装有间歇排水装置。通过采用上述技术方案，将排水口安装于计算得出的桥梁的最低点处，从而有利于将积水从排水口排出，提高了排水速率，并且减少积水在桥面上积累，减少对行车带来和桥梁的耐久性造成的影响。其中通过鹅型管形成强制虹吸，有利于提高积水通过鹅型管的速度，从而在虹吸作用下减少积水中的泥土、树叶等残留在鹅型管或集水槽中，起到防堵的效果，进一步有利于桥面排水。
